“What’s the difference between MP3-encoded sound and AAC-encoded sound? AAC became part of the MPEG-2 standard in 1997 to provide efficient encoding for surround sound audio. It supports up to 5.1 channels (Left, Center, Right, Left and Right Surround, plus a low frequency channel). Its quality at 64Kbps is comparable to MP3 at 128Kbps. MPEG-2 AAC is a continuation of the MP3 coding scheme. Like MP3, AAC exploits the psychoacoustic properties of human hearing, using sound-masking techniques to achieve efficient compression with very little noticeable degradation in audio quality. Finally, it provides a compression advantage of about 1.3 to 1.4 that of MP3 with better sound quality.”

I'm a passionate, long-time lover of Apple products, and was a civil draftsman and graphic designer before creating the iLounge web site. My prior projects include work for The Los Angeles Times' LATimes.com, and the company Creative Domain, where I developed websites for clients including Columbia Pictures, Disney, Fox Studios, Universal Pictures and Warner Brothers. As the Publisher of iLounge, I direct the site's community forums, photo galleries, iPod User Group, and general business affairs, which have grown under my watch to over sixteen million page views every month. I'm happily married with one daughter, one dog (Rocket the Wonderdog), one cat (Ferris), many iPods, iPhones, iPads, and two turntables.
